All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0017] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model. Furthermore, if terms such as "first" or "second" appear in the description of this utility model, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0018] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] As shown in the attached figure, the present invention includes a float 1 and a plurality of connecting rods 2 connected in series below the float 1. The connecting rods 2 are provided with a sampling chamber 3, and the sampling chamber 3 is provided with a sampling port and an air hole 5 respectively. A control valve 6 that can be opened and closed automatically is provided on the sampling port.

[0020] By default, control valve 6 is in the closed state. In this case, the buoyancy of float 1 is greater than the total weight of multiple connecting rods 2 and sampling chamber 3. The entire sampling device is placed in the water, and the connecting rods located below float 1 quickly extend underwater. Control valve 6 is opened, and water enters the corresponding sampling chamber 3 from each sampling port. Then, the sampling device is taken out of the water, and the water in each sampling chamber 3 is poured out and collected.

[0021] In this case, when collecting water samples from shallower surface areas, only one connecting rod 2 and sampling chamber 3 need to be connected below the float 1. If it is necessary to collect water samples from ponds or other water bodies at different depths, different numbers of connecting rods 2 and sampling chambers 3 can be connected as needed, allowing for simultaneous collection of water samples from various depths.

[0022] Preferably, float 1 is a solid foam float. It is lightweight and durable.

[0023] Furthermore, the top of the float 1 is equipped with a traction rope 7. The traction rope 7 facilitates the deployment and retrieval of the sampling device. A groove is provided around the circumference of the float 1, and the traction rope 7 can be wound around the groove when not in use.

[0024] Preferably, the connecting rod 2 and the float 1, as well as two adjacent connecting rods 2, are connected by threads.

[0025] The bottom of the float 1 is provided with a connecting part, and the connecting rod 2 is threadedly connected to the connecting part. All connecting parts can be quickly disassembled and assembled through threaded connection.

[0026] Preferably, the sampling chamber 3 is threaded to the bottom of the connecting rod 2, and the top of the sampling chamber 3 is open. The sampling port and the air hole 5 are located on the side wall of the sampling chamber 3, respectively. As a detachable independent component, the sampling chamber 3 can be quickly removed for collection after water quality sampling.

[0027] Preferably, the diameter of the pore 5 is smaller than the diameter of the sampling port, and the height of the pore 5 is higher than the height of the sampling port.

[0028] In this case, the diameter of the vent 5 is 1mm. When collecting water samples, the vent 5 can expel the air in the sampling chamber 3. After the air is removed, the vent 5 is insufficient to expel the rapidly flowing water in the sampling chamber 3. The diameter of the sampling port is 10mm. The diameters of the sampling chamber 3 and the connecting rod 2 are the same, both 50mm. The height of the sampling chamber 3 is 60mm, and the height of the connecting rod 2 is 400mm. A sampling chamber 3 is located at the top end of the connecting rod 2 at the top, which is used to sample the surface water.

[0029] Preferably, the control valve 6 includes a valve core 8, a tension spring 9, and a buoyancy ball 10. The valve core 8 is a conical valve core, and both ends of the valve core 8 are provided with a limiting edge 12. The tension spring 9 is sleeved on the valve core 8 and located inside the sampling chamber 3. The buoyancy ball 10 is connected to the valve core 8 located at one end outside the sampling port by a pull rope.

[0030] By default, the valve core 8 blocks the sampling port under the action of the tension spring 9, so that the sampling port is in a closed state. When it is put into the water, the buoyancy ball 10 floats up and pulls the valve core 8 outward. At this time, the sampling port opens and water enters the sampling chamber 3. When it leaves the water surface, the valve core 8 blocks the sampling port again under the action of the tension spring 9.
